Answer:
The correct option is D = regionNumber
Explanation:
In this scenario we want to know customers who owe more than $1000 each, in each of 12 sales regions. And the customer data variables include name, zip-code, balanceDue and regionNumber; based on the customer data variables names and zip-code will not really affect our output. It is based on balanceDue that we increment the number of customer owing in a particular region (regionNumber).
Therefore, we would add 1 to an array element whose subscript would be represented by regionNumber since we are interested to know the number of customer owing in each of the 12 sales regions.
Answer:
Explanation:
Network Access Control is needed to make sure that only set of verified users access the network.
It makes sure that the users are authenticated and only set of some verified users have access to network.
Set of NAC solutions like Impulse SafeConnect, Extreme Networks, ExtremeControl, Auconet BICS, ForeScout CounterACT, Pulse Policy Secure could be installed in the system which along with basic profiling will make sure authenticated access to the network.
Other than this basic encryption-decryption algorithm can be used in this regard. Network components could use encryption algorithms like RSA and DES. These algorithms will make sure that the information from database side is well encrypted. Once that information goes to the network component. They can decrypt the encryption by generating relevant key using the same algorithm.
This will only allow authentic users to access information and also it will stop the leakage of information in between the transmission because of encryption.
Answer:
You use an append query when you need to add new records to an existing table by using data from other sources. If you need to change data in an existing set of records, such as updating the value of a field, you can use an update query.
